Zypper Repository type can't be determined

Hmm. There’s obviously some disconnect with the use of
zypper with arg:
–releasever

And the proper format and arrangement.

We see three versions:

  1. zypper dup --releasever 16.0
  2. zypper --releasever 16.0 dup
  3. zypper releasever=16.0 (equal sign used)

The cited document shows #1 … so my guess is two of the three are rwong.

If #1 is rwong, then the documentation link is incorrect.
